5 Claims.

My invention relates to that type of drinking valves adapted to be putin the bottom of a reservoir for water, or in a pipe, to projectdownwardly so that poultry, rabbits and the like can drink directly fromsaid drinking valve, and without taking any part of the valve into theirmouths.

This application is a substitute for the application, Serial No.360,106, filed Oct. 7, 1940, and which has become abandoned.

Among the-salient objects of my invention are: To provide a drinkingvalve of the character referred to which is sensitive to the touch ofthe chicken or rabbit and at the same time so closes the outlet thatthere is no leakage or seepage of Water through said valve; to provide adrinking valve of the character referred to in which there is a doublevalve feature, one valve element being hard and the other of resilientmaterial; to pro,- vide in such a device a ball device projectingslightly through its valve seat, sufficiently to be engaged by the beakof the chick, or by the nose of a rabbit, so that the slightest touchwill move the valve slightly from its seat and will also engage andmove' the second valve up inside the body so as to permit water in avery small quantity to flow out through the valve body; to provide in adevice of the character referred to a ball valve in a valve seat whichwill not only close on the valve seat by gravity and by the pressure ofthe water above, but will be washed and kept clean from small particlesof food and foreign matter which might otherwise get into the valve seatand prevent tight closing of the ball valve.

Other objects and advantages of my invention will appear from thefollowing detailed description of one practical embodiment thereof,taken with the accompanying sheet of drawing, in which- Figure 1 is aview of a water pipe with my drinking valve therein;

Figure 2 is an enlarged view taken on line 22 of Fig. 1;

Figure 3 is a plan view of the drinking valve on line 33, Fig. 2; and

Figure 4 is a sectional view taken on line 4-4 of Fig. 2. i

Referring now in detail to the drawing, I have shown my drinking valveapplied to a water pipe 5, rather than showing it in the bottom of atank or reservoir. It is usually mounted in a pipe or in the bottom of areservoir sufficiently high so that poultry, rabbits, and the like canmove thereunder and by reaching their beaks up and touching the valvemember, it will be moved sufliciently to permit necessary leakage ofWater for drinking. It will be noted that the chick does not take thevalve in its beak, nor can it, for it projects only sufiiciently to beengaged by the point of the beak or by the nose of a rabbit.

The drinking valvein the shown embodiment, includes abody 6,.having athreaded end I, adapted to be screwed into the pipe 5, and having in itslower end a valve seat 8, in which is seated a ball valve 9.

Mounted within the body 6 is a, valve element Ill, having a passageway II therethrough, and having its upper end tapered or made conical, as atI2, and forming a conical valve seat on the upper end of said valveelement.

Mounted upon said. valve element I0.is a valve member I3, preferablymade of rubber, or other suitable resilient material, and having a stemportion I3 adapted to extend down through the passageway I i, and havingits head or upper end provided with an overlying, annular lip I4,adapted to fit down over the upper tapering or conical end of said valvemember I0, as indicated in the enlarged sectional view in Fig. 2.

The upper end of the valve body 6, is shown provided with three punchindents, at I5, I5, to prevent the valve member I3 from falling out whenthe assembled drinking valve is handled, shipped or the pipe is turned.

The inserted valve element i0 is designed to be pressed or forced intothe body 6, and is shown as seated on a slight annular shoulder formedin the body 6.

It will be seen that the water pressure will not only hold the valvemember I3 down on the conical valve element Iii, but that the waterpressure will also press the annular overlying lip I4 more tightly downover the tapered end of said valve element.

In operation, it will be understood that when a little chick, or anolder chicken, or a rabbit, or any other animal touches the ball valve9, it will raise it slightly, and in turn this will engage and lift thevalve I3 sufiiciently to unseat the annular lip 14 thereof, and thusallow water to seep to and through the valve e ement I0 and through thepassageway I I and into the lower part of the body 6, and around theball valve 9,

which tends to wash and keep said ball valve clean and free of dirt orsmall particles of feed.

Where there is constant seepage or leakage, it amounts to a considerableloss of water in time, but with my improved double valve feature, and myimproved construction and arrangement, I

have done away with all unintended leakage and have provided a valvewhich the smallest chick can easily operate and can drink directly fromthe ball valve as its beak is placed thereagainst.

This not only avoids waste of water, but it does away with the Wet,sloppy floor or ground under the pipe or reservoir.

I am aware that changes in details of construction and arrangement canbe made in my invention as here illustrated for explanatory purposeswithout departing from the spirit thereof, and I do not, therefore limitmy invention to the showing here made, except as I may be limited by thehereto appended claims.

I claim:

1. In a drinking valve, a body adapted to be connected with a source ofwater supply and having an outer end, a valve element seated in saidouter end, a seat Within said body, and a member seated on said seat andhaving a part engageable by said valve element, whereby said member isunseated upon inward movement of said valve element.

2. In a drinking valve, a body adapted to be connected with a source ofwater supply and having an outer end, a valve element seated in saidouter end, a seat within said body, and a member seated on said seat andhaving a stem portion extended through said seat and positioned to beengaged by said valve element when the latter is moved inwardly, wherebyto unseat said valve element and said member sufliciently to permitleakage of water.

3. A drinking valve adapted to be connected. with a source of Watersupply and having an outer I.

end, a floating valve element seated in said outer end to protrudetherethrough, a member within said valve forming a seat within the same,a valve element seated on said member and having a portion extendedthrough said member to be engaged by said floating valve element whenthe latter is moved inwardly, whereby to unseat said floating valve andsaid valve element within the valve to permit leakage of water throughsaid valve.

4, A drinking valve including a body to be connected with a source ofwater supply and having an outer end, a valve seat within said body ofconical form, a valve element within said body having an annularoverlying lip adapted to seat down upon said conical valve seat, wherebywater pressure seats said valve element down upon said seat and pressessaid annular lip upon said conical seat, said valve element having apart extending downwardly through said valve seat, and a floating valveelement in the outer end of said body adapted to be moved inwardly toengage with said part extending through the valve seat, whereby movementof said floating valve element inwardly by a chick moves said innervalve element to cause leakage of water from said body.

5. A valve mechanism including a body having means for connecting itwith a source of water supply and having a passageway therethrough, anannular valve seat of conical form in said passageway, a valve elementof flexible material within said body and seated upon said conical valveseat and having an annular overlying lip portion to fit down over saidconical valve seat with a portion extended through said annular valveseat, whereby water pressure seats said valve element down upon saidconical valve seat and presses said annular lip portion inwardly uponsaid conical seat, to prevent leakage through said body, and means inthe outer end of said body adapted to be moved inwardly by engagementtherewith, said inward movement causing said means to engage and movesaid valve element to cause leakage through said body.
